During his speech at the UN, the U.S. President welcomed the "progress" achieved by the Arab Spring, while deploring the anti-American violence shaking the Arab and Muslim world today. He also called for sanctions if the Syrian regime continues to "massacre its people. Barack Obama said Tuesday that the regime of Bashar al-Assad must be "terminated" in order to "put an end to the suffering of the Syrian people."

"The future does not belong to a dictator killing his people," Obama the General Assembly of the UN. He added that the Syrian regime would suffer "sanctions" if it continued to suppress opposition.

"If there is a case that should arouse protests across the world today, it is this regime that tortures its children and fires rockets into apartments," he added.

The international community, he said, must "ensure that what began with citizens claiming their rights does not end in a cycle of sectarian violence."

"We must side with the Syrians who have a different vision" of their country, "united Syria in which children have nothing to fear from their own government and where all Syrians have their say, Sunnis and Alawites, Kurds and Christians," Obama said."We believe that the Syrians who adopt this vision will have the strength and legitimacy to lead" the country.

To do this, the U.S. president called for "sanctions and consequences for those who persecute, help and support for those who work for the common good."

The U.S. President also welcomed the "progress" achieved by the Arab Spring, despite anti-American violence that shook the Arab and Muslim world for two weeks. "The events of the last two weeks show that we must honestly defuse tensions between the West and the Arab world and moving towards democracy," said the President of the United States.

Obama also denounced "an attack against America," citing the attack that killed the U.S. ambassador in Libya's Benghazi on September 11.
